Introduction to General Biology

Asexual

: organism produces offspring virtually identical to itself.

Metabolism

: all of the chemical reactions that occur inside your cells.

genetic material

Sexual: from 2 individuals unites to form new third individual.

Producer autotroph

: extract energy and nutrients from nonliving environment.

Producers

extract energy and nutrients from the nonliving environment.

Biosphere

(most complex): our planet earth- interactions between all ecosystems.

Homeostasis

: state of internal constancy or equilibrium (things can happen that disrupt your )

Decomposers

are consumers that obtain nutrients from dead organisms and organic wastes.

Community

: the interaction between all species in an area.

Consumer Heterotrophs

: eat other organisms for nutrients.

Ecosystem

: all of the living and nonliving interactions in an area.

Population

: a collective group in a particular area of the same species.

Mitosis

(cell division) is occurring all the time in our body: mainly used for cell renewal and repair; constantly making new cells.

Consumers

obtain energy by eating other organisms.

Molecules

: a combination of different atoms forming a larger structure- can be put together in a wide variety of complexities.

Atoms

(least complex): form the foundation- when they start interacting with each other they form the next level of organization.

Law of entropy

: energy is constantly lost as it travels through the atoms and molecules that make us up; process of energy lost.

Cells

: made up of thousands of organelles- not all have the same composition of organelles- grouping of different organelles together to form that self sustaining unit that can reproduce.

Decomposer

: obtain energy from wastes or dead organisms.

Cells

are the smallest unit of life that can function independently (if given the right environment)

Organelles

small structures that have a specific role of function in the cell

Tissues

different combinations of cells forms different types of tissues

Organs

different combinations of tissues

Organ system

combine organs to create an organ system

Organism

multiple organ systems working together to form a whole living unit

Population

a collective group in a particular area of the same species

Community

the interaction between all species in an area

Ecosystem

all of the living and nonliving interactions in an area

Metabolism

all of the chemical reactions that occur inside your cells

Law of entropy

energy is constantly lost as it travels through the atoms and molecules that make us up; process of energy lost

Producer/autotroph

extract energy and nutrients from nonliving environment

Consumer/Heterotrophs

eat other organisms for nutrients

Decomposer

obtain energy from wastes or dead organisms

Homeostasis

state of internal constancy or equilibrium (things can happen that disrupt your homeostasis)

Asexual

organism produces offspring virtually identical to itself

Sexual

genetic material from 2 individuals unites to form new third individual

Mitosis (cell division) is occurring all the time in our body

mainly used for cell renewal and repair; constantly making new cells

Recent issue of climate change

environments are changing so fast, species dont have time to adapt and survive -> causes ecosystems to collapse
